Volume ray casting, sometimes called volumetric ray casting, volumetric ray tracing, or volume ray marching, is an image-based volume rendering technique. It computes 2D images from 3D volumetric data sets. Volume ray casting, which processes volume data, must not be mistaken with ray casting, which processes surface data.

Famous quotes containing the words volume, ray and/or casting:
“There is a note in the front of the volume saying that no public reading ... may be given without first getting the author’s permission. It ought to be made much more difficult to do than that.”
—Robert Benchley (1889–1945)
“Our reason may prove what it will: our reason is only a feeble ray that has issued from Nature.”
—Maurice Maeterlinck (1862–1949)
“This I do know and can say to you: Our country is in more danger now than at any time since the Declaration of Independence. We don’t dare follow the Lindberghs, Wheelers and Nyes, casting suspicion, sowing discord around the leadership of Franklin D. Roosevelt. We don’t want revolution among ourselves.”
—Lyndon Baines Johnson (1908–1973)
